Its really difficult to remember live acts and the music that they play.
Some are :
Hallucinogen, most of his live acts
Slinky Wizard, Sola luna 2001
Red Seal, Sola luna 2001 , had perhaps the best sex in my life, girl that i met had her tent next to the chill area
Kox box, many of their live was awesome
and lots of other that i cannot remember. Use to attend psy parties every weekend till 2003. Generally best live acts that i heard were before 2002-03. Sad eh?
Also artists that i love and reaaaally looking forward to listen to them live and never had the opportunity is Ka-Sol/Derango and BOTFB..and i rarely listen to psytrance-goatrance the past years
